    Is 88 the same as 89?? 2.5 engine. Doing a changeover and a diagram would be helpful. Have the 88 shop manuals, but not the 89.

    Transferring engine/tranny from an 89 into an 88 Caravan. 2.5 engine.

    Most appreciative if someone here can help!!

    Attached is the PCM connector pin outs for 1989 Plymouth Acclaim / Dodge Spirit twins with 2.5 liter 4 cylinder engine. PCM pin outs are the same. Pin #6 and pin #46 on the 1989 version are used to supply information for the mini trip computer. Otherwise connector pins are identical with 1988 so you should not have a problem with the engine swap.

    1988-1989 Engine compartment wiring harnesses are functionally the same.

    Lots of Engine differences between the 1988-1989 2.5 TBI 4 cylinders.

    89 is common block with shorter timing belt, reverse rotation water pump etc.

    Exhaust pipe may need a slight tweeking.

    Thanks

    FYI: Doing a changeover in the swap. Taking out a 3.0 and installing a 2.5. Hate that 3.0. 3.3 better engine IMHO.

    Original post wasn't clear.

    "Transferring engine/tranny from an 89 into an 88 Caravan. 2.5 engine."

    Thanks
